Answer:
The best answer to the question: Anemia can be caused by a diet lacking in which nutritional substances?, would be, D: Folic acid and vitamin B12.
Explanation:
Anemia, is usually defined as a problem in the formation of red blood cells, or, erythrocites. Usually, there are a number of nutrients, such as vitamins and minerals, that play a vital role in the formation of these erythrocites. One such mineral is iron, which is why, when it is lacking in the diet, it can cause an anemia called iron-deficiency anemia. In this case, the anemia, which is either a reduced production of red-blood cells, or, cells that are incapable of carrying out their duty as oxygen-transporters, is caused by a dietary deficiency. Another form of this can be when the body itself, through an illness, is incapable of producing these cells. However, aside from iron, there are other two nutrients that are vital in the correct formation of erythrocites, and in their being efficent transporters: folic acid, also known as folate, and vitamin B12, both necessarily supplied by the diet, as the body cannot produce them.
Answer:
The correct answer is e. dermis
Explanation:
Lymph capillaries are thin walled capillaries interwoven with blood capillaries and found throughout the body except nervous system, bone marrow, and tissues that do not contain vascular tissue like epidermis.
The role of lymphatic capillaries is to collect the extra fluid which is secreted by the tissues in the intercellular spaces. This fluid is called lymph and is clear and transparent and contains WBCs and plasma.
Lymph is different from blood because it do not contain RBCs and platelets. Lymphatic vessels are important part of body immunity because it contains many WBCs in their lymph helpful in fighting diseases.
Answer:
For the majority of healthy individuals, normal blood sugar levels are as follows: Between 4.0 to 5.4 mmol/L (72 to 99 mg/dL) when fasting. Up to 7.8 mmol/L (140 mg/dL) 2 hours after eating.
The technique made by the nurse is keeping sterile field above waist level.
<h3>Which technique is made by the nurse to insert an indwelling urinary catheter?</h3>
Similar to an intermittent catheter, an indwelling urinary catheter is implanted, but it is left in place. A water-filled balloon keeps the catheter in the bladder and prevents it from escaping. These catheters are frequently referred to as Foley catheters.
The sole approved usage for indwelling urinary catheters is short-term, or fewer than 30 days (EAUN recommends no longer than 14 days.) Urine incontinence (UI) and urinary retention are two frequent bladder dysfunctions for which the catheter is implanted for continuous bladder drainage.
In order to produce a sterile field, sterile surgical drapes must be placed around the patient's surgical site and on the stand that will contain the sterile instruments and other supplies required for the procedure. The maintenance of a sterile environment is crucial to the prevention of infection. These collection of procedures that are followed before, during, and after invasive procedures help to lower the risk of post-procedure infection by reducing the number of potentially contagious microbes.
Hence, The technique made by the nurse is keeping sterile field above waist level.
